REG U LATOR.

SPECIFICATION forming part of Letters Patent No. 450,719, dated April 21, 1891.

Application filed May 19, 1890- Serial No. 352,344. (No model.)

T0 all whom it may concern.-

Be it known that I, ELMER A. ALsDURF, a citizen of the United States, residing at Spartansburg, in the county of Crawford and State of Pennsylvania, have invented a new and useful Regulator, of which the following is a specification.

This invention relates to regulators more especially adapted for use in connection with apump driven by suitable power, as a windmill; and the object of the invention is to effect improvements on devices of this character heretofore existing.

To this end the invention consists in devices, as hereinafter more fully described, and as illustrated in the accompanying drawings, in which Figure l is an elevation of the well, the pump, the tank, and the regulating devices, showing the latter properly connected and in then correct relative positions. Fig. 2 is a side elevation, and Fig. a central longitudt nal section, of the float-valve. Fig. 4: is a perspective detail of the clapper of the float. Fig. 5 is a side elevation of the pressure-regulating cylinder. I

Referring to the said drawings, \V is the well or cistern, from which rises a pump-tube 1, having a mouth M and a branch tube P, adapted to deliver water into a tank or other reservoir T. The water is raised through the pump by means of a rod R, operating a lift or force valve V at the lower end of the pump, which rod is driven by suitable power. The power in the present instance is a windmill mounted upon the supports S, although it will be understood that this power may be steam, electricity, or any other force suitably controlled.

Coming now to the present invention, 1 is an ordinary three-way cock mounted upon the pump-tube P, and is a branch pipe leading from said cock to a check-valve Q, (best seen in Fig. 1,) whence the water passes through a tube aito the pressure-cylinder 5, (best shown in Fig. 5,) and also up the pipe P to the tank T. The said three-way cock 1 may be operated by a handle having a rod connected thereto and led to any suitable point, or the valve in this cock may be omitted entirely, making it an ordinary three-way coupling. As the water is raised through the tube P, it may thus be caused to flow through the mouth M of the pump or through the branch pipe 2, up the tube P, and through the valve 3 to the tank and also through the tube 4; to the pressure-cylinder 5.

The relative positions of the parts, as shown in Fig. 1, may be changed considerably without eilecting any material change in the successful operatior of the entire regulatingdevice.

6 is a Heat in the tank T, which float is connected by a rod or chain 7 with a crank-arm 8 upon the shaft 0 of the valve 3, which shaft carries an arm 10, having a head 11 at its outer end adapted to close against a seat 12 in the valve-casing when the float rises. The said head 11 is provided with holes 13 through its body, and hinged on the inlet side of this head is a flap-valve 14, adapted to close the holes 13. 7

20 is a piston within the cylinder 5, and the piston-rod 21 of this piston is connected by a yoke 22 with a rod 23, guided in an eye 24, carried by a supporting frame-work 25 of the cylinder. The said frame-work has clips 20, which embrace said cylinder tightly, but may be loosened when it is desired to set the cylinder axially. The latter has an opening 27 near its upper end above the uppermost position of the piston 20, and the tube 4 is c011- nected with this opening. The weight of the piston, piston-rod, yoke, and depending rod 23 is sustained and counterbalanced by a weight 28, connected by a chain 29, leading overa pulley 30, suitably journaled in the framework 25, the chain being connected to the lower end of the depending rod 23.

The water is lifted through the pump, as above described, and gradually fills the tank T, whereby the lloat is slowly raised. As it is raised, the head 11 in the valve 3 is closed more and more, and the water flowing through the branch pipe 2 is also directed into the tube 4: to the pressure-cylinder 5. \Vhen the water has reached the highest desirable point in the tank, the valve 3 is completely closed, and the full force of the water falls against the flap l-i and closes that also. The pump still working and the water finding no exit from the pipe P into the tank, it sets back through the branch pipe and considerable pressure is communicated to the cylinder.

This force causes a certain pressure in the cylinder above the piston, which pressure forces the piston downward and draws on a cord or chain 50, connected to the upper end of the piston-rod 21, as will be understood. This chain connects with a windmill, engine, or other source of power, and when drawn upon stops the motion of the same, and hence ceases to work the pump. WVhen the water in the tank T is partlydrawn off at any point above the check-valveQ, (which drawing off is permitted by the flap 14,) the float 6 falls, and as it falls it permits the opening of the head 11 in the valve 3, which opening is caused by the outwardly-flowing water. This drawing off reduces the pressure within the cylinder and the opening of the valve 3 of course breaks the pressure, and in either event the piston rises and the pumpresumes its work. It will thus be seen that the rising and falling of the water in the tank automatically starts and stops the pumping mechanism.

What I claim is- 1. The pressurecylinder herein described, the same comprising aframe-work 25, having clips 26, and also having a pulley and an eye 24, a cylinder within said clips, a piston 20 Within the cylinder, a piston-rod 21, leadin g therefrom, a yoke 22, connected therewith, a depending rod 3, extending from the outer end of said yoke through said eye, a chain 29, passing from the lower end of said depending rod over said pulley, and a weight 28 at the free end of said chain, substantially as set forth.

2. In a regulator, the combination, with a tank, a pump provided with a check-valve in its tube leading to the tank, a valve in said pump-tube operated by a float within the tank and closing toward the tank, and a downwardly-opening flap on the inlet side of the head of said valve, of a pressure-cylinder, a pipe connecting its upper end with said tube above the check-valve, a piston in said cylinder whose piston-rod is connected with the regulating devices of the pump-operating mechanism, and a faucet within said tube above the check-valve, substantially as described.

3. In a regulator, the combination, with a tank, a pump provided with a check-valve in its tube which leads to said tank, a valve in said pump-tube operated by a float in the tank and closing toward the tank, a pressurecylinder and a pipe connecting its upper end with said tube above the check-valve, of a piston in said cylinder whose piston-rod is connected with the regulating devices of the pump-operating mechanism, avertically-moving rod connected with said piston-rod, a chain leading from the lower end of said rod over a pulley, and a weight attached to said chain, the whole adapted to operate substantially as described. a

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
